TABLE 5-1: Boiler Troubleshooting Procedures

FAULT

INDICATION

PROBABLE CAUSES

CORRECTIVE ACTION

PRG SWTCH
CLOSED
DURING
IGNITION

1.

A/F Valve rotated open to purge and did not
rotate to ignition position.

2.

Defective or shorted switch.

1.

Start the unit. The Air/Fuel Valve should rotate to the purge (open)
position, then back to ignition position (towards closed) during the
ignition cycle. If the valve does not rotate back to the ignition
position, check the Air/Fuel Valve calibration. If calibration is okay,
the problem may be in the Air/Fuel Valve or the C-More Controller.
Refer fault to qualified service personnel.

2.

If the Air/Fuel Valve does rotate to the ignition position, check the
purge switch for continuity between the N.O. and COM terminals.
If the switch shows continuity when not in contact with the cam,
check to ensure that the switch is wired correctly (correct wire
numbers on the normally open terminals).

PRG SWTCH
CLOSED
DURING
IGNITION

(continued)

3.

Switch wired incorrectly.

4.

Defective Power Supply Board or fuse.

5.

Defective IGST Board.

3.

If the switch is wired correctly, replace the switch.

4.

Check DS1 & DS2 LEDs on Power Supply Board. If they are not
steady ON, replace Power Supply Board.

5.

Check “Heartbeat” LED DS1 and verify it is blinking ON & OFF
every second. If not, replace IGST Board.

PRG SWTCH
OPEN
DURING
PURGE

1.

Defective Purge

switch.

2.

No voltage present at switch.

3.

Switch wired incorrectly.

4.

Defective Power Supply Board or fuse

5.

Defective IGST Board.

1.

If the air-fuel valve does rotate, check Purge

switch for continuity

when closing. Replace switch if continuity does not exist.

2.

Measure for 24 VAC from each side of the switch to ground. If
24VAC is not present, refer fault to qualified service personnel.

3.

Check to ensure that the switch is wired correctly (correct wire
numbers on the normally open terminals).

4.

Check DS1 & DS2 LEDs on Power Supply Board. If they are not
steady ON, replace Power Supply Board.

5.

Check “Heartbeat” LED DS1 and verify it is blinking ON & OFF
every second. If not, replace IGST Board.

RECIRC PUMP
FAILURE

1.

Internal recirculation pump failed.

1. Replace recirculation pump.
